(Cl. 242-433) Thisinvention relates to a new and improved winding machine more especiallydesigned for winding yarn, thread and the like, such as silk, wool,cotton, rayon, etc.

The usual method of winding such material'is to provide a bobbin mountedon a rotating spinthe speed of the traverse is to a certain extentlimited, due to the necessity of. successively rais-' ing or elevatingthe traversingplane, and an ob-.

ject of this invention is to provide a construction of winding machinewhich can be run at-almost any desired speed, due to the fact that thetra- 2 verse guide always remains in one plane.

sides in the fact that the traverse plane of the thread-guide is notcontinuous and the operation is not positive and smooth, and anotherobject of this invention is the provision of a construction in whichtheelement which receives the material being wound, as for instance abobbin, is caused to move continuously, positively and uniformly, withrespect to the unchanged traversing plane of the thread-guide,

Another advantage of this invention resides in the fact that the angleof the thread from its usual guide to the traverse guide remains withinthe limits of the traverse, whereas this angle is constantly changing inpresent types of machines wherein the traverse guide is beingsuccessively raised to accomplish the building of the package beingwound.

This change of angle in' present machines causes a constant change intension on the thread to its disadvantage, particularly in the windingof material, such as rayon. Furthermore, such a change in tensionresults in a package of uneven density. Other objects and advantagesrelate to the size, shape and relation of the parts, all as will morefully appear in the following description taken in connection with theaccompanying drawings,

in which:

Figure 1 is a vertical section through my device.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on line 3-3, Figure 1. Figure 4 is a sectionshowing certain parts in' elevation on line 4-4, Figure 1. Figure 5 is asection on line 55 of Figure 1.

In the drawings I show a base --1 having A further difliculty withpresent machines resecured thereon an upwardly extending frame -2 havingopposed bearing-supports -3-- and -4. 0n the upper surface of bearing-The inner end of. shafts8- carries a beveled gear 13 secured thereto bya set screw 14-.

A worm--15 is securedto-shaft -8- between bearings 9-- and 10-. a

' A second shaft 16.is' journaled in a bear- --17- in bearing-support--3 and carries on its inner end a beveled gear --18 secured thereto bya set screw --19. The outer end of shaft -16- is provided with a,crank-arm 20- secured thereto by a set screw 21--. A link --22 has oneend *pivotally mounted on crank-arm 20 by' means of pivot pin .--23--and has its'other end pivotally mounted-in a yoke 24- secured to thelower; end-of a reciprocating shaft --25- jou'rnaled in threadguidesupport -5-. The upper end. of shaft-'5 has secured thereto athread-guide --2'7 by means of a set screw 26-.

A bobbin-shaft 28- has its lower end journaled in the base ofbearing-support -2-, preferably by means of a ball bearing -29. A ballbearing 30-- positioned in the upper end of bearing support -2-- acts asan intermediate bearing for shaft 28.

A beveled gear -31- is keyed to shaft 28- beneath bearing --30-- and iscontinuously in mesh with gears --13- and 18-. The upper end -32 ofshaft 28 is square in crosssection, and extends upwardly through anaperture 33- in bearing-support 34-. Aperture -33- is sufficiently largein diameter to permit the free rotation therein of end 32-- of shaft 28.

Bearing support -34-- is secured in the main bobbin support --35 by aset-screw -36-. A 105 ball bearing --37 is held in position on the upperend of bearing support -84 by a bearing-cap --38-.

A bobbin-spindle -39 carries a downwardly extending shank --40 journaledin bearing e -3'land is provided with a curved spring --4lhaving itsopposite ends extending outwardly through slots in bobbin-spindle --39.Bobbin-spindle 39- is provided with a central aperture square incross-section, and of a size to receive the upper end 32 .of shaft 28which is slidably, but not rotatably mounted therein.

The outer end of main bobbin support --35-- is slidably mounted onguides 42- and 43- carried on the upper end of frame -7-. A pulley 44 isrotatably mounted on the upper end of frame ---7- above mainbobbin-support 35. A counterweight 45 is secured to one end of a cable46- which passes over pulley l4- and has its other end secured to mainbobbin support 35- to support the weight of the latter.

A threaded shaft -47 has its lower end journaled in a bracket 48 securedto frame -7--, and carries adjacent its lower end a worm gear 49-continuously in mesh with worm 4-15- on shaft -8-. Threaded shaft 47-extends upwardly through a split nut --50-- whichis held againstrotation in a cage 51- carried on main bobbin support 35-.

The opposite halves 52- and SB-bf split nut 50 are provided respectivelywithppin's 54- and ---55. p and -55, are slidably mounted in a plate--56-- and the other ends of pins 54- and 55 extend outwardly intocurved slots --57- and 58- in a pivoted plate 59-. .An operating handle60 is attached to plate 59-. When plate 59 is pivoted pins 54 and 55will move in slots 57- and 58- and will be forced outwardly to disengagesplit nut 50- from threaded shaft 47- so that the main bobbin support 35may be moved vertically independently of threaded shaft 47-.

Operation When it is desired to wind a cop on a bobbin, a bobbin 61 isplaced in position onbobbin spindle '39-. I have shown as illustrative,a solid cylindrical bobbin, but obviously a bobbin of my desired formmay be used and the bobbin may be perforated, if desired; Split nut--50- is then opened and main bobbin support 35- is moved verticallyuntil the lower end of bobbin 61 is in line with thread guide 27- withshaft 25-- in the downward position. Split nut 50- is then closed intoengagement with threaded'shaft 4'7--. The thread to be wound (none herebeing shown) is then passed through thread guide --27 and around thelower end of bobbin 61.

With the parts in this position, shaft 18- is caused-to revolve from anyconvenient source of power (none here being shown) with the result thatthrough gears 13-- and 31- shaft 28-- will be made to revolve, andinasmuch as the upper end 32-- of shaft 28-- is in operative engagementwith bobbin spindle --39--, the spindle 39- will also be caused torevolve, carrying with it bobbin 61, which is held securely on spindle39- through the action of spring 41- which is in resilient engagementwith the inner surface of bobbin 61. The rotation of bobbin 61 willcause the thread to be drawn through thread guide 27 and wound on bobbin61.

The rotation of shaft 8-- will, through gears -13, 31- and 18 cause therotation of shaft --16 with a resulting rotary movement of crank arm20-. The.rotary movement of crank-arm 20- will through link 22- and'ment of said guide. One of the ends of pins 5.4-

tation in cage 5lon main bobbin-support 35-, split nut -50- and mainbobbin support 35- will be moved downwardly, carrying with them bobbin61-. This downward movement of bobbin 61- past thread guide 2'7- will becontinueduntil the upper end of bobbin 61- is in line with thread guide27, when the latter is in the raised position. When this movement hasbeencompleted, the machine will be stopped so that the bobbin with thecop thereon maybe removed and a new one substituted for a repetition ofthe cop-winding operation.

In Figure 1 I ha veshown inheavy lines a thread-guide 2'7-- in thedownposition, and

in dotted lines thread-guide 27-- in the raised position as illustrativeof the traversing move- I have also shown in dotted lines the shapewhich the cop will have when it has been wound on bobbin -61, the copbeing thicker at the central part than at the end because of the factthat the reciprocating movement of thread guide 27- combined with thecontinuing downward movement of bobbin 61- will progressively increasethe number of overlapping threads from the lower end "of the bobbin,

cally with relation to each other, but it will be understood that asimilar result will be obtained if the parts are arranged so that theywill move horizontally or in any other direction, provided only thatthey move in substantially parallel relation.

It will also be understood that the mechanical means for obtaining myresult may be variedto a considerable extent without departing from thespirit of my invention, and although I have shown and described aspecific structure and form of parts thereof as an exemplification orembodiment of my invention, I do not desire to restrict myself to theexact size, shape, or relation of parts, as various changes may be madewithin the scope of the appended claims.
